Voices - is there any documentation or established know-how on these?

I want to know (and are in the process of figuring out) what is actually needed for the post-campaign, freestyle playing.

E.g. I don’t think that the base name entries in the voices of people in bars are actually used (“Welcome to Gas Miner Naha”) are used. So, we don’t need to create new entries for new base names for these voices.
